Relax. Rating has just started. By default, itch.io is randomly shuffling all games for each request. Hit F5 and you will see.

The best way to get feedback is rating & commenting the games of other Jammers. That's an important part of the Game Jam experience anyway, so you should make use of it.

What will keep others from playing your game, is a missing version than can be played directly in the browser. So if you  want to  give  players an easy way to access and your game, you should take this option into account.
